Log4j2 - debug-level logging except for Spring

Question

I'd like my application to run at Debug level, except for Spring, which is producing a huge amount of logging statements, which makes it hard to read through the logs. I've currently configured my Log4j2 file like this:

<Configuration status="debug">
    <Appenders>
        <RollingFile name="systemLog" fileName="C:/test/logs/system.log" includeLocation="true"
                    filePattern=""C:/test/logs/system-%d{MM-dd-yyyy}-%i.log.gz">
            <PatternLayout pattern="%d{ISO8601} - %-5level [%t] %C %M %m%n" />
            <Policies>
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="15 MB"/>
            </Policies>
        </RollingFile>
        <Async name="systemAsyncAppender" includeLocation="true">
            <AppenderRef ref="systemLog" />
        </Async>
    </Appenders>
    <Loggers>
        <SpringLogger name="org.springframework.*" level="error" additivity="false">
            <AppenderRef ref="systemAsyncAppender" />
        </SpringLogger>
        <Root level="debug" includeLocation="true">
            <AppenderRef ref="systemAsyncAppender" />
        </Root>
    </Loggers>
</Configuration>

I thought that setting up the SpringLogger would set Spring to only run at ERROR level and, and write to the same log as everything else, but I'm still seeing full Spring DEBUG output. I have vague memories of being able to do this very easily with the old log4j.properties files (I think it was as simple as log4j.category.org.springframework=ERROR), but I'm not sure how to do this with Log4J2.

(Using Log4J2 2.0.2, spring 3.2.11)

Answer 1

I don't think log4j2 has any special configuration for Spring, so <SpringLogger> doesn't seem appropriate here.

Instead, just declare a regular logger

<logger name="org.springframework" level="error" additivity="false">
    ...
</logger>

Also note the logger name. These are hierarchical. You don't need the * (and I think it actually breaks it).
